Explanation:
The law of sines is
This is the same as writing
Because we apply the reciprocal to each side to keep things balanced
Note how the 'a's stick together on one side, so do the 'b's and 'c's.
For something like 
we can see the 
portion, but now there's an 'a' in there. This is from multiplying both sides of the equation below by 'a'
The summary is that the 'a' pairs with sin(A) and that's what matches with expression number 1.
--------------
For expression number 2, we'll have it pair with sin(B). This is because the 'c's already are taken care of (they are paired up) and there's an extra b all by itself. The working/steps will basically look like what is shown in the section above, though you'll use the equation 
Expression 3 will match with sin(C) for similar reasons as expression 2. The 'c' is the only letter that isn't paired up.
The other expressions will match in similar fashion. The filled out answers are shown in the attached image below.
Answer:
D
Step-by-step explanation:
Answer:Perimeter is the limit of any given geometric figure. Circumference is just the name given to a circle’s perimeter, in other words, the circle’s limit, its edge.
The reason for this is because the perimeter is, by definition, the sum of the lenghth of every side of any given geometric figure. A circle has either no sides, or number of sides, so its perimeter has to be treated differently.
Remember that π (Pi) equals 3.141592 approximately. This is a constant, meaning that no matter what circle you are studying, Pi will always have the same value. It is the relation between the diameter and the lenght of its circumference. A circle with diameter xwill travel 3.141592x before it completes a revolution. This is where Pi comes from.
So the difference would be that a “normal” perimeter is only the sum of the sides. A circumference is the perimeter of a circle, given a diameter and the constant value of Pi, that derives from other properties of the circle, and not by its sides (remember a circle has either none or nnumber of sides).
× greater than 1 is the answer I believe.
